I am with you. We had DS tested at 4 and he scored a 130 but the tester said he was probably higher b/c he wouldn't do the easy questions. On Dr. Ruf's scale he is probably a 3 or 4 and he is currently working 3 to 6 grades above his age level. So, we had ds now 7 tested again by the same tester and he scored a 120. He had also tested when he was in Kindergarten public school and was place into the GT program. So, I have chalked it up to an off day.
